Deroyal LMB Acu-Spring Finger Extension Assist is ideal for regaining last few degrees of PIP extension. Finger Extension Assist is designed for increasing PIP extension that is restricted by joint tightness or flexion contractures. The assist can be bent to accommodate mild swelling and it extends the MP joint slightly. To find the right size, measure on volar surface from distal palmar crease to distal finger crease.

Acu-Spring Finger Extension Assist Key Points:

  • 6 lbs of force at 90 degrees of flexion
  • Single patient use only
  • Adjustable tension
  • Latex free

More Information

  • Directions For Use
  • - Select the correct size.
    - To fit the spring, slide splint onto finger so the proximal pad rests over the volar aspect of the metacarpal head and the distal pad rests at the distal interphalangeal joint (DIP).
    - To adjust spring tension, there are two options:
    - To increase the force of extension, spread the volar pads apart before placing on the finger.
    - To decrease the force of extension, pinch the volar pads together before placing on the finger.
